SPINDLE AND FLIER.

SPECIFICATION forming part of Letters Patent No. 349,709, dated September 28, 1886.

Application filed July 18, 1884.

To all whom it may concern:

Be it known that 1, JOHN Goon, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Spindles and Fliers, of which the following is a specification.

My invention relates to closed fliers and their spindles, such as are employed in spinning rope-yarn and for making twine. In machines of this class theflier and spindle are commonly driven by separate belts from two pulleys on a counter-shaft driving onto two pulleys, one fast on the flier-journal and the other locked fast to the spindle, so that the spindle and its pulley turn in unison. The flier has a uniform speed of rotation, but as the bobbin on the spindle increases in size the spindle should turn slower, and more power is required to drive it, because of the increasing leverage which the yarn or twine exerts to retard the bobbin, and which must be overcome to maintain a uniform tension on the yarn or twine.

In order to provide for imparting the necessary variable movement to the spindle and bobbin it has been customary to employ a friction-drag consisting of a disk or flange and a pulley having faces which are in frictional contact one with another, whereby the necessary slip between the pulley and the disk or flange is provided for.

.My invention relates to machines in which the friction device or drag is arranged directly in the spindle and flier,instead of upon a counter-shaft, ashas also been done heretofore.

Important objects of my invention are to re duce the number of bearings necessary for the spindle and flier and to provide a very com pact arrangement of the bearings for the flier, the spindle, and the flier-driving pulley and friction-disk; also, to provide amore desirable means than that heretofore in use for transmitting the movement of the traverse motion to the bobbin.

The invention consists in the combination, with a spindle and flier, of a pulley on the flier-journal for driving the flier, a loose pulley concentric with the spindle for driving it, and a friction device or drag interposed between the spindle-pulley and the spindle itself.

The invention also consists in the combina tion, with a spindle and a flier having a tubu? Serial No. 138,042. (No model.)

lar journal at its driving-head and a driving pulley fast thereon, of a spindle-driving pulley having a long sleeve fitting and turning in the interior of the tubular \journal of the flier and receiving the spindle through it; also, in the combination, with the foregoing, of a friction-disk working against a face provided in the spindle-pulley, locked tothe spindle, and having a tubular sleeve receiving the spindle through it, and fitting and capable of turning in a recessed portion or counter-bore in the sleeve of the spindle-pulley, as more fully hereinafter described.

The-invention also consists in the combination, with a closed flier, fixed bearings for the journals thereof, and a hollow slotted spindle fitting bearings at opposite ends of the flier a vertical longitudinal section of a spindle and fliersuch as are commonly used in jenny for spinning rope-yarnsand means for driving them, embodying my invention. Fig. 2 isa back view of the friction disk or flange and a transverse section of the spindle, showing the means whereby they are locked together. Fig. 3 is a back view of the bobbin-coupling and a transverse section of the spindle and traverse rod; and Fig. 4 is a longitudinal section on a larger scale, illustrating the driving-head of the flier and the driving mechanism for the spindle and flier, also including the bearing for the driving-head journal.

Similar letters of reference designate corre sponding parts in all the figures;

A designates the flier, having at one end the capstan-head A and journal B, and at the other end the driving-head A and journal B. The journal B consists of or is formed by a hollow hub or sleeve, which is fitted to a bearing, a, in a suitable frame, 13 and on which is formed or secured a flier-driving pulley, O. The journal B at the capstan-head A of the flier is fitted to a bearing, a, on the frame B and is tubular, so as to receive through it the shaft or stem or of the capstan-pinion, on which is a pulley, a

D designates the spindle, which has a-suitable bearing, a, in the capstan-head A of the flier, and is made hollow or tubular nearly or entirely from end to end.

E designates the bobbin, which is fitted to slide on the spindle, but is locked to turn therewith, as I shall soon describe, and F designates a spindle-driving pulley, which is concentric with the spindle and the flier-journal.

The pulley F is constructed with a long tubular sleeve, F, which is fitted to the interior of the hollow flier-journal B, and is afforded an adequate bearing therein. From its inner end outward for about half its length the sleeve F is bored to fit the spindle D, and while the said sleeve is itself afforded adequate bearing in the flier-journal B it affords ample bearing within it for the spindle. From the outer end of said pulley-sleeve F inward for about half its length there extends thereinto a recess or counterbore, b, and on the outer side of the pulley F is a friction face or surface, 12.

G designates a friction disk or flange which bears against the face I), and is preferably faced with leather. or other material to make frictional engagement with the pulley F. The friction disk or drag G, which is fitted to and afforded ample bearing in the recess or counterbore 12, receives the spindle D through it. The spindle-pulley F, though it receives the spindle through it, is not locked thereto, but the friction disk or drag is locked to the spindle, so as to drive the same.

The spindle here shown has lugs or ears 0 at opposite points, and in the hub of the disk or flange Gr are notches 0, which receive said lugs or ears and engage with them to drive the spindle.

The bobbin E is attached to a bobbin-coupling, E, also fitted to slide on the spindle D and detachably connected by means of an ear and slot, 0" 0* with the bobbin E.

H designates the traverse rod, which is fitted to slide within the hollow spindle D, and is moved therein longitudinally by any wellknown traverse motion connected with its outer end, H. This to-and-fro traverse motion may be produced by means of a screw having crossed threads of reversed pitch engaging a swiveled nut-section or fork carried by the sleeve, through which the screw extends, as is shown in my Letters Patent N 0. 317,116, dated May 5, 1885. The hollow spindle D is slotted at d for the greater part of its length, and the head H at the inner end of the rod H projects through this slot and is permanently connected with. or attached. to the bobbin-coupling E by a screw or other suitable means. The bobbinooupling is locked to the spindle by the head H, passing through the slot (1. The pin-and-slot connections 0 0* between the bobbin and its coupling are well known, and are of such form that when the bobbin is turned ahead slightly relatively to the coupling it may be separated therefrom.

I designates a counter-shaft, which is driven by a belt, I, over a pulley, I and on said counter-shaft are two pulleys, I I, from which belts I I drive onto the pulleys O F, which transmit motion to the flier and spindle. The pulleys I I are fast on the counter-shaft I, and the effects of the friction device or drag are transmitted directly to the spindle without any variation, and a uniform tension will be producedon the yarn or twine as it is wound on the bobbin. These important results are due entirely to the arrangement of the friction device or drag in the spindle and flier, and cannot be obtained when a belt is interposed between the friction device or drag and the spindle, as has been the case heretofore.

As the bobbin increases in diameter by the winding of the yarn or twine upon it the disk or flange G must be pressed more strongly against the friction-face of the pulley F, in order to overcome the increasing resistance to the rotation of the bobbin.

J designates a forked lever fulcrumed at 'e, and having a bearing on the hub of the disk G. The lower end of this lever is connected by a rod,J, with the short arm of abalance-beam,J

which is fulcrumed at e, and the long arm of 5 which has an attached screw-shaft, J on which is suspended a weight, J The screw-shaft J derives a slow rotary motion by a worm-wheel, e", and worm 0 from a cross-shaft, e, and this shaft 6 is rotated by belt or gearing from any convenient shaft of the machine. I The weight J'* has a knife-edged bearing on the screwshaft J ,and as the size of the bobbin increases the weight is moved outward on the long arm of the lever by the slow rotation of the screwshaft. As the weight J* moves-outward it exerts a greater pressure of the disk G against the friction-face of the pulley F, and so exerts a greater power to turn the bobbin and spin dle.

The mechanism above described for applying a gradually increasing pressure of the disk G on the pulley-face is well known in connection with machines having the friction device or drag on a counter-shaft and a belt interposed between the friction device and spindle, and I do not therefore claim the same, broadly.

On the counter-shaft I is still another pulley, I from which a belt, 1 drives onto the pulley a? on the shaft (1 of the capstan-pinion.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a spindle and flier, ofa pulley on the flier-journal for driving the flier, a loose pulley concentric with the spindle for driving it, and a friction device or drag interposed between the spindle-pulley and the spindle itself, substantially as herein head and a driving-pulley fast thereon, of aspindle-driving pulley having a long sleeve fitting and capable of turning in the tubular journal of the flier and receiving the spindle through it, substantially as herein described.
